Check Digit Verification of cas no

The CAS Registry Mumber 16749-44-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,7,4 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 16749-44:
(7*1)+(6*6)+(5*7)+(4*4)+(3*9)+(2*4)+(1*4)=133
133 % 10 = 3
So 16749-44-3 is a valid CAS Registry Number.

ON THE SELECTIVITY OF DEPROTECTION OF BENZYL, MPM (4-METHOXYBENZYL)AND DMPM (3,4-DIMETHOXYBENZYL) PROTECTING GROUPS FOR HYDROXY FUNCTIONS

Horita, Kiyoshi,Yoshikoa, Tadao,Tanaka, Tatsuyoshi,Oikawa, Yuji,Yonemitsu, Osamu

, p. 3021 - 3028 (2007/10/02)

The 4-methoxybenzyl (MPM) protecting group for hydroxy functions is readily removed with DDQ in dichloromethane containing a small amount of water at room temperature.Under these neutral conditions, several other protecting and functional groups remained unchanged. 3,4-Dimethoxybenzyl (DMPM groups are more reactive than MPM groups with DDQ.The benzyl (Bn) protecting group was removed by catalitic hydrogenation over Raney nickel.Selective deprotection of DMPM, MPM and Bn groups is also presented.
